It should be noted that: like reference numerals refer to like items in the following figures, and thus, once an item is defined in one figure, it may not be further defined or explained in subsequent figures.

The length of a rod connected to a connector of the existing back posture corrector cannot be adjusted, and the existing back posture corrector cannot be suitable for trainers with different body sizes and heights. The utility model discloses mainly to this technical problem, design out the back posture unscrambler of length adjustable of a rod, will explain in detail two kinds of length adjustment structures through two embodiments below, but not limited to following two kinds of structures, specifically as follows:

example one

As shown in fig. 1 to 6, the back posture corrector 100 comprises a connector 10 and two sticks 20 connected to the connector 10, wherein the two sticks 20 are crossed to form a cross structure, so that the back posture corrector can correct the back posture of the trainer. Each stick 20 comprises a middle tube 21 penetrating through the connector 10 and an extension tube 22 sleeved at the outer end of the middle tube 21, and the caliber of the extension tube 22 is larger than the outer diameter of the middle tube 21, so that the extension tube 22 is sleeved outside the middle tube 21 and can move back and forth relative to the middle tube 21 to achieve the effect of unfolding or extending the stick 20. Wherein fig. 1 is a schematic view of a deployed state of a pole 20 on a back posture corrector 100, and fig. 2 is a schematic view of a retracted state of a pole 20 on a back posture corrector 100.

Specifically, as shown in fig. 3 to 5, a damping member is disposed on the middle tube 21, the damping member and the inner wall of the telescopic tube 22 have a sliding damper 30, the damping member is an end cap 23 disposed at the outer end of the middle tube 21, the end cap 23 includes an inner end t1 having a smaller outer diameter and an outer end t2 having a larger outer diameter, the inner end t1 of the end cap 23 is inserted into the inner hole of the middle tube 21, and the inner end t1 of the end cap 23 is fixed to the middle tube 21 by clipping.

The outer end t2 of the end cover 23 is positioned at the outer side of the middle pipe 21, and the outer end t2 of the end cover 23 and the inner wall of the telescopic pipe 23 are provided with a sliding damper 30; so that the intermediate tube 21 and the telescopic tube 22 are kept in a relative movement position.

The advantage of this embodiment is that the two sticks 20 on the connector 10 are of a telescopic structure, and include a middle tube 21 and a telescopic tube 22 sleeved on the outer end of the middle tube 21, and the telescopic tube 22 is moved back and forth along the length direction of the middle tube 21, so as to achieve the effect of adjusting the overall length of the sticks 20; after the length of the rod 20 is adjusted, the middle tube 21 and the extension tube 22 can be locked relatively, so as to prevent the extension tube 22 of the trainer from moving relatively to the middle tube 21. The same posture correcting device 100 can be suitable for trainers with different heights and body types, and the telescopic structure can reduce the packaging volume and save the storage and transportation cost.

It should be further noted that the end cap 23 is fixedly connected to the sliding damper 30, and the outer diameter of the sliding damper 30 is larger than the diameter of the intermediate pipe 21. The sliding damper 30 is made of elastic plastic or rubber, the sliding damper 30 is always clamped on the inner wall of the telescopic tube 22, and one end of the end cover 23 is fixed on the middle tube 21, so that the middle tube 21 and the telescopic tube 22 are always positioned on the same straight line and cannot shake up and down, left and right. Based on the technical means, when the trainer uses the device, the middle tube 21 and the extension tube 22 are kept at relative moving positions, and the extension tube 22 cannot slide relative to the middle tube 21 accidentally because of the trainer in the process of correcting the back posture. When telescoping is desired, the trainer needs to apply a certain amount of lateral force to wand 20 to overcome the friction between slide damper 30 and telescoping tube 22 to move telescoping tube 22 inwardly or outwardly.

Preferably, a reducing sleeve 24 is mounted at the inner end of the telescopic tube 22, and the reducing sleeve 24 cooperates with the end cap 23 to limit the telescopic tube 22 from being detached from the middle tube 21. Specifically, the outer diameter of slide damper 30 on the side of end cap 23 is greater than the outer diameter of reducing sleeve 24, and when extension tube 22 is extended by moving outward relative to intermediate tube 21, the inner end wall of slide damper 30 and the inner end of reducing sleeve 24 are defined with each other to prevent extension tube 22 from being removed from intermediate tube 21.

As shown in fig. 12, the connector 10 includes a first connecting holder 11, a second connecting holder 12, and a shaft pin 13, and the first connecting holder 11 and the second connecting holder 12 are connected by the shaft pin 13 and make both the connecting holders rotatable. The first connecting seat 11 is provided with a first through hole p1 for the middle tube 21 of the first stick to penetrate through, and the second connecting seat 12 is provided with a second through hole p2 for the middle tube 21 of the second stick to penetrate through. The shaft pin 13 sequentially and radially passes through the middle pipes 21 of the first roller and the second roller; thereby combining the two connecting seats and the two sticks 20 into an integral structure. The first connecting seat 11 and the second connecting seat 12 can rotate relatively, when training is not needed, the two connecting seats can rotate relatively to drive the two sticks to fold and be in a parallel and close state, and therefore the space occupied by the back posture corrector is reduced.
